  • Sale
  • Regular price $1,795.00


The S54 T4 Tubular bottom-mount turbo manifold is a mid-mount design that places the turbocharger strategically in the E46 engine compartment. This is also an upgrade to your current Horsepower Freaks bottom-mount Turbo-kit. Limitations within the cast bottom-mount and plate manifolds, this tubular version will aid in spool and carry your turbochargers abilities throughout the entire RPM range.

**This manifold comes Open T4 flange and no wastegate port.  Wastegate should be welded onto turbine housing as shown in pictures.  Turbine housing is not included but can be added in the drop-down menus.**
